Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule 

This Rule was amended mainly to remove a reference to a rule that is not in the SIP. Also, test methods were 

updated and their full titles were included (per EPA guidance). The rule is intended to satisfy the requirements of 

the 2008 CTG for Miscellaneous Metal and Plastic Parts Coatings. The adoption resolution and staff report for the 

previous version of the Rule included a Negative Declaration for plastic parts coating operations since none that 

would be subject exist in the NSAQMD. The amended Rule also includes minor improvements to the Definitions 

section, minor changes to improve enforceability and the addition of “etching fillers” to the acid content 

measurement section (5.5). 

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2 

 (CO) PM TAC (name):Variable, depending on 

formulations of coatings

Emissions Reduction Commitment in the SIP for the Control Measure: N/A 

Revised Baseline Inventory (if any): N/A 

Revised Emission Reduction Estimate (if developed): N/A 

Note that the district’s input to the Rule Evaluation Form will not be used as input to the ARB’s emission forecasting and 

planning. 

III. SOURCES/ATTAINMENT STATUS 

District is: Attainment Nonattainment Split 

Approximate Total Number of Small (<100 TPY) Sources Affected by this Amendment: 1

Percent in Nonattainment Area: 100% 

Number of Large (> 100 TPY) Sources Controlled: 0 Percent in Nonattainment Area: N/A% 

Name(s) and Location(s) (city and county) of Large (> 100 TPY) Sources Controlled by Rule (Attach additional sheets as 

necessary): N/A 

IV. EMISSION REDUCTION TECHNOLOGY 

Does the Rule Include Emission Limits that are Continuous? Yes No 

If Yes, Those Limits are in Section(s) N/A of the Rule. 

Other Methods in the Rule for Achieving Emission Reductions are: Several emission reduction mechanisms are ioncluded 

in the rule: 1) Optional control equipment with 90% VOC control efficiency; 2) Work practices, including clean-up practices, 

to minimize emissions; 3) VOC content limits for coatings and solvents; 4) Test methods; 5) Detailed recordkeeping 

requirements and labeling requirements to ensure compliance. 

V. OTHER REQUIREMENTS 

The Rule Contains: 

Emission Limits in Section(s): N/A Work Practice Standards in Section(s): 3.3, 3.4, 3.5 

Recordkeeping Requirements in Section(s): 4.2 Reporting Requirements in Section(s): 4.2
